"This season we've had great success with our new hit series The Originals paired with Supernatural, giving us our best Tuesday nights in years," CW President Mark Pedowitz said in a statement. "The Vampire Diaries is No. 2 in its time period in the young adult demos, and with Arrow continuing to gain among young men, and Reign growing its time period, we now have strong nights on Tuesday, Wednesday and Thursday. I'm very pleased to announce early pickups for all five series, and let our fans know they'll have more great drama to look forward to next season."

Freshman series The Originals and Reign have fared well this fall, debuting to 2.24 million and 1.98 million, respectively. Meanwhile, Supernatural has seen big year-over-year growth, jumping 88 percent in total viewers to 3.2 million viewers in its ninth season. In its second season, Arrow has become the network's most-watched series, averaging 3.9 million viewers, while The Vampire Diaries is the highest-rated show for the network in key demos during its fifth season.
